As shown in figure 1, the invention discloses a kind of mass-rent express delivery path allocation methodology based on subway network, this method bag
Include following steps：
S1, the OD routing informations to subway each service time section are counted, and are expected according to statistics and variance
Computing, filters out all energy one according to operation result and jumps through OD paths interval；
It is S2, interval based on the OD paths that can go directly, it is given it is estimated deliver success rate under conditions of, OD paths interval is searched
Rope sets gradually different predicted transmission time conditions, and selection meets the OD combination of paths under the most short delivery time of demand；
Wherein, the OD paths are the path between subway any starting station O and either objective website D.The OD paths
Interval is the OD paths under some time interval.
In step sl, the OD routing informations of subway each service time section are counted, the departure date is entered according to statistics
Hope and variance computing, filtering out all energy one according to operation result jumps through OD paths, you can through OD paths are interval.
For each starting station O and targeted sites D because stand-by period and run time were changed over time in one day,
Some OD can be caused to meet transmission demand within the shorter period, and can be failed in longer time section.
For example, more in peak period period certain site flow of the people, variance now is smaller, can meet transmission demand.
And if the record of a whole morning is taken into account, due to peak period after at the time of flow of the people it is less, train interval is also longer, most
The overall variance calculated eventually may also be larger, does not meet transmission demand.So, in the present invention, it is necessary to be divided into not one day
Same time interval statistics, the smaller current probability reflected of a time interval is also more accurate；Further, since expecting and variance
Need to calculate by certain data volume, each interval again can not be too small.
The present invention marked off a time interval by one day by per half an hour, and each OD is counted not according to historical data
Expectation and variance with interval transmission time.Transmission time includes stand-by period and running time, and the former parcel is waited
The time that suitable passenger arrives, the latter represents that passenger takes the time that parcel is arrived to passenger away.Running time can be from
Directly extracted in subway history OD records, and calculate the expectation and method for taking each OD in the different time interval downward driving time.Deng
The time of the treating speed that can be arrived at a station with passenger is estimated that the reciprocal of passenger's number represents stand-by period, such as 30 that is, in the unit interval
Averagely there are 10 passengers in minute, the average latency is 3 minutes.Because stand-by period and running time are relatively independent, one
The expectation of OD transmission time and variance are to wait for time expectation and expect sum, stand-by period variance and row with running time respectively
Sail time variance sum.
One time interval includes initial time, the end time, the average of transmission time, the information such as transmission time variance.
If some interval record number is very few, it is believed that current interval is unreachable and is removed from it.The result so generated is institute
There is the interval routing information for being capable of the through OD of a jump.
In step s 2, it is interval based on the OD paths that can go directly, under conditions of given estimated delivery success rate, in order to the greatest extent may be used

Under conditions of number, the search element interval to OD paths sets different predicted transmission times, is such as sent within 1 hour, is sent within 2 hours, and
The interval delivery success rate in OD paths under the predicted transmission time is obtained, selection meets predicted transmission time and it is expected that thrown simultaneously
Pass the OD combination of paths of success rate.
In summary, the routing issue in subway express delivery network can be defined as giving a start site O and point of destination
Point D, it is contemplated that time C, if selecting suitable bang path to cause parcel can be with certain probability P within the estimated time
It is sent to destination.The output of problem is all periods that can be sent in meet specifying constraint one day, and accordingly
Expense.Due to expense and hop count positive correlation, expense can be replaced to export with hop count here.
Further, as shown in Fig. 2 the invention discloses a kind of mass-rent express delivery path allocation side based on subway network
Method, this method comprises the following steps：
S1, the OD routing informations to subway each service time section are counted, and are expected according to statistics and variance
Computing, filters out all energy one according to operation result and jumps through OD paths interval；
It is S2, interval based on the OD paths that can go directly, it is given it is estimated deliver success rate under conditions of, OD paths interval is searched
Rope sets gradually different predicted transmission time conditions, and selection meets the OD combination of paths under the most short delivery time of demand；
S3, it is given estimated deliver success rate and predicted transmission time under conditions of, each OD paths interval is carried out many
Route search is taken turns, the delivery success rate in OD paths interval is obtained, selection meets estimated delivery success rate and anticipated transmission simultaneously
The minimum OD combination of paths of hop count under time conditions；
Wherein, the OD paths are the path between subway any starting station O and either objective station D, and OD paths interval is
OD paths under different time is interval.
In step sl, for each starting station O and targeted sites D because stand-by period and run time are in one day
Change over time, some OD can be caused to meet transmission demand within the shorter period, and in longer time section
It can fail.
For example, more in peak period period certain site flow of the people, variance now is smaller, can meet transmission demand.
And if the record of a whole morning is taken into account, due to peak period after at the time of flow of the people it is less, train interval is also longer, most
The overall variance calculated eventually may also be larger, does not meet transmission demand.So, in the present invention, it is necessary to be divided into not one day
Same time interval statistics, the smaller current probability reflected of a time interval is also more accurate；Further, since expecting and variance
Need to calculate by certain data volume, each interval again can not be too small.
The present invention marked off a time interval by one day by per half an hour, and each OD is counted not according to historical data
Expectation and variance with interval transmission time.Transmission time includes stand-by period and running time, and the former parcel is waited
The time that suitable passenger arrives, the latter represents that passenger takes the time that parcel is arrived to passenger away.Running time can be from

Hour is sent to, and obtains the interval delivery success rate in OD paths under the predicted transmission time, and selection meets anticipated transmission simultaneously
Time and it is expected that the OD combination of paths of delivery success rate.
In step s3, in order to reduce transfer number of times as far as possible, in given estimated delivery success rate and predicted transmission time
Under conditions of, many wheel route search are carried out to each OD paths interval, each round limits different maximum hop counts.And obtain in OD
The interval delivery success rate in path, selection meets that estimated to deliver hop count under the conditions of success rate and predicted transmission time minimum simultaneously
OD combination of paths.
In order to minimize transfer number of times, under conditions of given estimated delivery success rate and predicted transmission time, the present invention
The interval route in each OD paths is calculated by carrying out many wheel route search, each round limits different maximum hop counts.Each round
The middle maximum hop count of search adds 1 successively, and it is interval only to search for all current inaccessible OD paths.The search result base of latter wheel
In previous round, i.e., it is the jump of OD paths interval extension one of transfer website by previous round destination, calculating new OD paths interval is
It is no completely to deliver demand.If new OD paths interval meets delivery demand, it is marked as reachable, is not required to search in round below
Rope.It is the separate time to be ridden due to passenger, for a bang path A->B->For C, it is contemplated that overall transmission time
By the average transmission time E's (AB) and E (BC) in two sections of paths and it can be estimated, i.e. E (AC)=E (AB)+E (BC),
And the variance in path is also the variance sum in each section of path, i.e. D (AC)=D (AB)+D (BC).If E (X) and D (X) difference tables
Show expectation and the variance of estimated time of delivery, under conditions of estimated time of delivery is C, the delivery success rate in path can pass through meter
CalculateObtain, wherein C=E (X)+ε, derivation is as follows：
If OD path interval has a plurality of OD combination of paths all to meet delivery and required under the same conditions, selection is thrown
Pass that maximum OD combination of paths of success rate.
In summary, the routing issue in subway express delivery network can be defined as giving a start site O and point of destination
Point D, it is contemplated that time C, if selecting suitable bang path to cause parcel can be with certain probability P within the estimated time
It is sent to destination.The output of problem is all periods that can be sent in meet specifying constraint one day, and accordingly
